.SH DESCRIPTION
\fIchannel\fP - Previously opened channel instance such as returned by
.BR libssh2_channel_open_ex(3)

\fIterm\fP - Terminal emulation (e.g. vt102, ansi, etc...)

\fIterm_len\fP - Length of term parameter

\fImodes\fP - Terminal mode modifier values

\fImodes_len\fP - Length of modes parameter.

\fIwidth\fP - Width of pty in characters

\fIheight\fP - Height of pty in characters

\fIwidth_px\fP - Width of pty in pixels

\fIheight_px\fP - Height of pty in pixels

Request a PTY on an established channel. Note that this does not make sense
for all channel types and may be ignored by the server despite returning
success.
.SH RETURN VALUE
Return 0 on success or negative on failure. It returns
LIBSSH2_ERROR_EAGAIN when it would otherwise block. While
LIBSSH2_ERROR_EAGAIN is a negative number, it is not really a failure per se.
.SH ERRORS
\fILIBSSH2_ERROR_ALLOC\fP - An internal memory allocation call failed.

\fILIBSSH2_ERROR_SOCKET_SEND\fP - Unable to send data on socket.

\fILIBSSH2_ERROR_CHANNEL_REQUEST_DENIED\fP -
